    Water Tube Boiler | Operation and Types of Water Tube

    Mar 04, 2020 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. Advantages of Water Tube Boiler

    Water Tube Boiler - Definition, Components, Working

    A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

    Water-tube boiler - Wikipedia

    A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.

    Finding the Root Cause of Boiler Tube Failures

    Components typically affected: During outage periods, flooded or non-drainable surfaces, such as superheater loops or sagging horizontal superheater and reheater tubes and supply lines, are most susceptible; also, when poorly deaerated water is used for startup or for accelerated cooling of a boiler. On operating boilers, it is most prevalent near pre-boiler feedwater heaters and economizers.

    Open the feed water valves and the air valve. Fill the boiler with feed water to approximately 50 mm below normal water level. The water level rises due to expansion when the boiler is heated. If the temperature difference between the boiler and feed water exceeds approximately 50ºC, the boiler must be filled very slowly.

    Before starting the fire, fill the boiler to the normal level with treated, deaerated water. Leave a vent open to prevent pressure build up during the dry out period. Maintain the water level to replace any that leaves the drum due to the heating process. Next, ensure that the furnace has been adequately purged.

    With far less mass (water content) than fire-tubes, the Rite boiler are able to generate steam much faster from a cold start. In addition, the drying tubes produce high quality saturated steam with less than 1% moisture content. This type of boiler eventually found acceptance across the rest of North America and has never looked back.
